CS48L10-CNZ

CS48L10-CNZ is a Cirrus Logic “smart amplifier” IC designed for portable audio. It combines a high‑efficiency Class-D speaker amplifier with on‑chip digital signal processing and a control interface, streamlining audio subsystem design.
Key capabilities (high level):
- Supports digital (I2S/TDM) and/or analog inputs
- Built‑in DSP for volume, EQ, limiting, and protection
- Speaker protection and fault handling
- I2C/SPI style control for programming and status
Typical use:
- Drives small speakers in phones, wearables, headsets, and embedded audio devices
Suffix note:
- The -CNZ suffix indicates a specific package/temperature variant; check the datasheet for exact details.
For exact electrical specs (supply, output power, interfaces, timing, thermal limits), refer to the CS48L10 data sheet on Cirrus Logic’s website. If you share your project needs, I can pull out the most relevant specs.

Direct cross-reference for CS48L10-CNZ isn’t published. Closest feature-set equivalents within Cirrus Logic’s CS48/CS47 families include CS48L22, CS47L24, and CS47L35 (audio DSP + amplifier + mic bias). For an exact cross, provide your required specs (I/O, DSP, power, package) and contact Cirrus Logic for an official cross-reference.
